Tripp Lite's SU80KX (80kVA) SmartOnline Modular 3-Phase Intelligent, True On-Line UPS System provides 100% system availability with N+1 modular architecture and 1+1 parallel capability. In N+1 configuration, the SU80KX provides four self-contained, redundant 20kVA power modules that can be hot-swapped (load remaining powered) if maintenance is required. In 1+1 configuration , two SU80KX models connected in parallel can provide fail-safe redundancy (two 80kVA models supporting a 80kVA load) or increased capacity (two 80kVA models supporting a 160kVA load). Large capacity 80,000VA/64,000W UPS continually converts incoming AC power into filtered DC power, and then resynthesizes it back into AC power with a pure sine wave. Hardwire input and output connections support a variety of permanent or PDU-style power connections. Frequency is 50 or 60 Hz (auto-selectable).
